Description Robb Gatica 2024-03-28 21:04:04 UTC 
Description:
In `@backstage/backend-common` prior to versions 0.21.1, 0.20.2, and 0.19.10, paths checks with the `resolveSafeChildPath` utility were not exhaustive enough, leading to risk of path traversal vulnerabilities if symlinks can be injected by attackers. This issue is patched in `@backstage/backend-common` versions 0.21.1, 0.20.2, and 0.19.10.

Note: the fix for this issue is already incorporated in RHDH 1.1.x.
